Flourescence material and white light illumination element |
摘要 |
A fluorescence material and a white light illumination element are provided. The white light illumination element includes a light emitting diode (LED) chip, a first fluorescence material, and a second fluorescence material. The LED chip is configured on a substrate and emits an exciting light. The first fluorescence material and the second fluorescence material are configured on the LED chip. A composition of the first fluorescence material includes an aluminum nitride oxide doped with at least one of europium (Eu) and manganese (Mn). A first emitted light emitted by the first fluorescence material after the first fluorescence material absorbs the exciting light emitted from the LED chip and a second emitted light emitted by the second fluorescence material after the second fluorescence material absorbs the exciting light emitted from the LED chip are mixed to generate a white light.
